The karsts of Sulawesi Tenggara cover an area of around more than 5,000 km2 in the south-east of the island of Sulawesi, Indonesia. They include the Matarombeo massif, a completely unexplored, vegetation-covered mineral fortress, and the Sombori-Labengki archipelago, rich in rocky islets and coral reefs, and populated by fishing villages.
The Matarombeo massif
The Matarombeo karst covers an area of around 1,200 km2, roughly the size of the island of Martinique, with its eponymous peak reaching an altitude of around 1,500 metres. It is bordered to the north and south by two main rivers that flow from west to east along the entire length of the massif. These waterways offer the possibility of approaching the entire length of the massif and creating natural transects.
In addition, together with the adjacent massifs of Tangkelemboke and Mekongga, the karsts of southeast Sulawesi still shelters one of the largest expanses of primary forests on the island, one of the last bastions facing palm oil, pepper and cocoa plantations, cement factories and nickel mines.
As karst massifs are known to be the richest areas on the planet in terms of biodiversity, the almost total lack of knowledge about the Matarombeo and surrounding rivers guarantees immense potential for discovery in terms of underground networks and species new to science.
The karstic complex of Sulawesi Tenggara juts out into the sea to the east at Sombori archipelago. Made up of a multitude of coves and rocky islets that are reminiscent of tourist sites in Southeast Asia, the beauty of the area and the richness of the underwater world have earned it the nickname “little Raja Ampat” , auguring future tourism development.
While the islands and coastline are dotted with a multitude of small villages that make their living mainly from artisanal fishing, the region has not been spared from plastic waste pollution and the unbridled exploitation of natural resources such as nickel.
